Choosing the right violin size is essential for a comfortable playing position and good technique. Especially for children who are still growing, it's important that the violin fits their height and arm length. This blog post explains step-by-step how to calculate violin size and what to look for.
Why the right size is so important
A violin that is too large makes it difficult to press the strings properly, which can lead to a child learning incorrect posture or becoming tired quickly.
On the other hand, a violin that is too small can reduce playing comfort and limit tone development.
The right size makes playing not only easier, but also more fun — and that motivates you to keep practicing.
How do you measure the correct violin size?
The size of a violin is determined by the length of your left arm , from the neck to the palm of your hand. This measurement provides a reliable indication of the correct violin size.
🔹 Step-by-step plan:
- Have the student stand or sit upright.
- Extend the left arm straight out in front of you (not up).
- Measure the distance from the neck to the center of the palm with a measuring tape.
- Compare the measured length with the table below.
Overview of violin sizes and arm lengths
| Violin size | Age (indicative) | Arm length (from neck to palm) | Body height (average) |
|---|---|---|---|
| 1/16 | 3 – 5 years | approx. 35 – 38 cm | up to 100 cm |
| 1/10 | 4 – 5 years | approx. 38 – 40 cm | 95 – 105 cm |
| 1/8 | 5 – 6 years | approx. 40 – 43 cm | 105 – 115 cm |
| 1/4 | 6 – 7 years | approx. 44 – 47 cm | 115 – 125 cm |
| 1/2 | 7 – 9 years | approx. 48 – 52 cm | 125 – 135 cm |
| 3/4 | 9 – 11 years | approx. 53 – 56 cm | 135 – 145 cm |
| 4/4 (adult size) | from 11 to 12 years old | from 57 cm | from 145 cm |
💡 Tip: Are you unsure between two sizes? Choose the smaller one. It's better for a violin to be a little too small than too big.
Additional points of interest
- Try different sizes: Sometimes a child will feel more comfortable with a slightly smaller or larger violin, depending on their build or flexibility.
- Don't forget the bow: The bow length should also suit the violin size.
- Have a teacher or violin maker observe: A professional opinion prevents wrong choices.
Summary
To determine the correct violin size, measure the arm length from neck to palm and compare this with a standard size chart.
A well-fitting violin ensures more playing pleasure, better technique and prevents injuries or frustration.
